How decisions unfold in a zebrafish brain

Some things we do appear almost automatic, like opening the fridge when feeling hungry or flipping on the air conditioning when the temperature rises. Although such decisions don’t seem to take much thought, they are in fact generated by millions of neurons and numerous interactions among several brain regions—a dynamic system so complex that scientists aren’t able to observe it […]

How dying cells prevent dangerous immune reactions

Dying cells in the body can keep the immune system in check, thus preventing unwanted immune responses against the body’s own tissues. Scientists from the German Cancer Research Center have now identified a receptor on murine immune cells that activates this protective mechanism and can thus prevent dangerous autoimmune reactions in which the immune system attacks the patient’s own body […]

New model explains how our immune system sometimes helps cancer spread

Dementia study reveals how proteins interact to stop brain signals

Fresh insights into damaging proteins that build up in the brains of people with Alzheimer’s disease could aid the quest for treatments. A study in mice reveals how the two proteins work together to disrupt communication between brain cells. Scientists observed how proteins—called amyloid beta and tau—team up to hamper key genes responsible for brain messaging. By changing how genes […]

How does protein fit in your holiday diet or New Year’s resolutions?

While some diets load up on protein and other diets dictate protein sources, it can be hard to know what to consume while managing weight or during weight loss. A new study by Purdue University nutrition scientists shows that eating more protein daily than what is recommended may benefit only a few—those who are actively losing weight by cutting calories […]
